Our memory begins to decline after the teenage years. Memories, those scattered fragments in our minds that seem true or false, will develop in the direction we want, and then gradually fade away from our minds. One day we will forget some things and even doubt whether some things really existed. Therefore, these days I am always thinking of writing something to prove the authenticity of some things. I also thought about where to leave it for a long time. Finally, I decided to put it here, and every ink stain would at least have traces and evidence of its existence.
